Photofly?
Or Colonal Saunders V 2.0? I know he posted a terrible thing about you awhile back but I thought it was just a passing comment.
I agree with what you posted in general, but I thought this was about power off or power on landings?
Not approaches.. So many types of aircraft (single engine) that is a bit hard to generalize, but,
if you are talking power on approach at best glide speed plus 10, then you can simply reduce or add a bit of power just as easily as pitching the nose up or down a bit.. If you mean power off, or on a forced approach you have to temper your genralization a bit I think. At best flide speed plus 10, partidularily in a small single , you might actually get a bit better range if you are flying into a headwind.. And if no headwind, you will not be getting the range you could at best glide speed.
So...if you hold best glide speed (no head wind) and you come up short, you go to plan B.
If you are going to land long, then you can raise the nose a bit (not really my choice in a forced landing situation), use flaps, or, if the aircraft can be sideslipped, do that..
There is also the human factor if we are drifting into the forced approach..When it happens for real, all that silly FTU drills, secures, restarts etc, tend to go out the window...the object is to fly the plane and get it safely into a field..Dont fancy it up. That is OK for pilots who do these types of things every day, but they are not the typcial single engine pilot.. My thoughts are KISS...Nail your best glide speed, see how things look and progress and then make any speed change decisions if they will work.
In any event, this thread was not about that, but as there are so many types of airplanes with different landing characteristics, Cat's original question does not welcome vast generalizations.
One of the difficulties we have with new CPL's is trying to get them to stop attempting to fly a new type like they did the last type they flew. It is important for pilots to understand that there are differences that they must adjust their flying technique to..
So power at idle, vs. power at touchdown...Depends...and that is the best answer anyone will give.
